What is The Third Day Of The Week?

by oaeen

The structure of the week is a cornerstone of human timekeeping, deeply embedded in the cultural, religious, and social fabric of societies worldwide. The third day of the week, typically known as Tuesday in many Western calendars, holds unique significance and connotations that have evolved through history. This article delves into the origins, historical significance, cultural interpretations, and contemporary relevance of the third day of the week, providing a comprehensive exploration of its place in human civilization.

Origins of the Seven-Day Week

Babylonian Roots

The seven-day week has its roots in ancient Babylonian astronomy. The Babylonians observed a seven-day cycle based on the phases of the moon, with each week corresponding to one-quarter of the lunar month. This cycle was deeply tied to their religious and astrological beliefs, with each day dedicated to a different celestial body known at the time: the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn.

Judaic Tradition

The Judaic tradition, as documented in the Hebrew Bible, also adopted the seven-day week. The Book of Genesis describes the creation of the world in six days, with God resting on the seventh day, the Sabbath. This religious framework not only reinforced the seven-day cycle but also imbued it with spiritual significance, influencing the structure of the week in Jewish culture and later in Christian and Islamic societies.

Roman Adoption and Adaptation

The Romans adopted the seven-day week from the Babylonians and named the days after their gods, corresponding to the celestial bodies. This practice became widely established during the reign of Emperor Constantine, who endorsed Christianity and established Sunday as a day of rest and worship. The Roman adaptation solidified the seven-day week in Western civilization, leading to the naming conventions we use today.

Tuesday: The Third Day in Context

Etymology and Naming Conventions

In the Gregorian calendar, which is the most widely used civil calendar today, Tuesday is the third day of the week. The name “Tuesday” derives from Old English “Tiwesdæg,” named after the Norse god Tiw (or Tyr), associated with war and combat. This naming convention parallels the Latin “dies Martis,” named after Mars, the Roman god of war, indicating a common cultural theme of associating the day with martial strength and courage.

Other languages reflect similar associations:

French: Mardi

Spanish: Martes

Italian: Martedì

German: Dienstag (from the god Tiw or Tyr)

These linguistic connections underscore the shared Indo-European heritage in the naming of the days and the persistence of ancient mythological influences in modern languages.

Astrological and Mythological Significance

In astrology, Tuesday is governed by Mars, the planet named after the Roman god of war. Mars is associated with energy, drive, and assertiveness, qualities that align with the themes of combat and strength. This astrological influence is thought to imbue Tuesday with a dynamic and action-oriented energy, making it an auspicious day for initiating projects and tackling challenges.

Historical Events on Tuesdays

Throughout history, significant events have occurred on Tuesdays, reinforcing the day’s association with action and decision-making. Here are a few notable examples:

The First Flight of the Wright Brothers

On December 17, 1903, a Tuesday, the Wright brothers made their first successful powered flight in Kitty Hawk, North Carolina. This historic event marked the beginning of the aviation era, transforming transportation and warfare.

The Assassination of John F. Kennedy

November 22, 1963, a Friday, saw the assassination of U.S. President John F. Kennedy, a pivotal moment in American history. However, the subsequent investigation and the profound impact on American politics and society unfolded over the following days, including significant developments on Tuesdays.

Cultural and Religious Practices


In Christianity, Tuesday does not hold the same level of significance as Sunday (the Sabbath) or Friday (Good Friday, commemorating the crucifixion of Jesus Christ). However, it is considered a regular day for worship, prayer meetings, and various church activities.


In Jewish tradition, Tuesday is considered a lucky day. This belief stems from the Book of Genesis, where the phrase “and God saw that it was good” is mentioned twice on the third day of creation (Genesis 1:10, 1:12). This double blessing has led to Tuesday being viewed as an auspicious day for new beginnings and important tasks.


In Islam, Tuesday is known as “Yawm Ath-Thalatha” and, like other weekdays, it is a day for regular prayers and activities. Specific religious practices or significances associated with Tuesday are not as pronounced as those for Friday (Jumu’ah, the day of congregational prayer).

Contemporary Perspectives and Practices

Business and Productivity

In the modern workweek, Tuesday is often seen as a highly productive day. After the adjustment period of Monday, employees and students typically hit their stride by Tuesday, making it an ideal day for meetings, project kick-offs, and intensive work sessions. Various productivity studies have indicated that Tuesday is one of the most productive days of the week, with many people reporting high levels of focus and energy.

Pop Culture and Media

Tuesday has also found its place in popular culture and media. For instance, in the United States, “Super Tuesday” refers to the day when the greatest number of U.S. states hold primary elections and caucuses during presidential election years. This day is crucial for candidates to gain momentum and secure their party’s nomination.

In the entertainment industry, Tuesday was traditionally the release day for new music albums in the United States, though this has shifted to Friday in recent years to align with global release practices.

Global Variations in Week Start

While Tuesday is widely recognized as the third day of the week in many cultures, variations exist globally based on different calendar systems and cultural practices. Understanding these differences provides a broader perspective on the significance of the third day.

ISO 8601 Standard

The International Organization for Standardization (ISO) defines Monday as the first day of the week, making Wednesday the third day according to ISO 8601. This standard is used in much of Europe and international business contexts, reflecting a more secular approach to the week’s structure.

Cultural Variations

In some cultures, Sunday is considered the first day of the week, making Tuesday the second day. For example, in Middle Eastern countries like Israel and in parts of the Christian tradition, Sunday holds this position, altering the sequence and perceived significance of the days.

Astrological and Psychological Interpretations

Astrological Influence

Astrologically, Mars’ influence on Tuesday is thought to encourage action, initiative, and assertiveness. This can manifest in both positive and negative ways, driving individuals to pursue goals with vigor but also potentially leading to conflict or impulsiveness. For those who follow astrology, understanding this influence can help in planning activities that align with these energetic qualities.

Psychological Impact

The psychological impact of associating certain traits with specific days can be significant. Belief in the special qualities of Tuesday can enhance motivation and productivity, as individuals feel more confident tackling challenges on this day. This phenomenon, known as the “placebo effect,” highlights the power of belief and perception in shaping behavior.

Tuesday in Literature and Arts

The third day of the week has also made appearances in literature and the arts, often symbolizing action, conflict, or turning points in narratives.

Literary References

In literature, Tuesdays can represent pivotal moments or significant events. For example, T.S. Eliot’s “The Waste Land” mentions Tuesday in the context of the poem’s broader themes of disarray and transformation. The choice of Tuesday here may symbolize a crucial but turbulent day within the poem’s narrative structure.

Visual Arts and Music

In visual arts and music, days of the week, including Tuesday, are sometimes used to convey specific moods or themes. Songs like “Ruby Tuesday” by The Rolling Stones evoke emotional and temporal imagery, linking the day to feelings of nostalgia and change.
